With the Prius, treatment of the battery is *critical* to longevity. 
Cooling, for instance, is a critical feature of Lithium Ion batteries 
and the early Prius' had an Achilles Heel in that regard. The battery 
cooling system had a critical vent at the back seat area and it was 
possible for the owner to accidentally block this with stuff placed 
carelessly in the back seat/floor area. Also, if you run a Prius at very 
high highway speeds, the Hybrid battery won't get charged by the hybrid 
charging system *or* regeneration. If that happens, and the battery goes 
dead flat, you won't be able to start or drive the car. The charging 
system will need a recalibration/cell balancing in order to get it 
functioning again.

I'm sure I mentioned this point in another post!  ;-)

Well, how odd, I too have a friend with a 12 year old Prius. Oops, no, 
it's now 13 years old.  ;-)  It's a 2010 model.

Anyway. be careful mentioning having *friends* around here, you'll be 
pilloried. I guess it's because those doing the pillorying don't have 
any friends or understand the concept of *having friends*.

Invariably some aspect of maintenance, cooling or operation is 
responsible for a good proportion of those. The first generation Prius 
had a few issues, as mentioned above but the issue was addressed by 
Toyota early on and reliability has markedly increased.

Well, according to carsales.com.au, a 2010 Prius is valued at $9000 to 
$15000 depending on condition. Given the Prius engine is 
*understressed*, one could expect it to do 300k-400k kilometres without 
requiring an overhaul if properly serviced. A Prius hybrid battery can 
be replaced for $2,000 - $4,500, you work it out on the *residual* value 
of the car.

> Either way the cost is high.

Bullshit. You will recoup the battery cost in fuel cost savings over the 
life of the battery. Likely *half* the expected battery life. It's a 
value judgement whichever way you address it.
